Coastal Accumulative Forms

relief forms that take shape within the boundaries of seashores through the accumulation of marine detritus. Sea waves and surf are the main factors in their formation. The forms may be shaped as a result of transverse (ledges) or longitudinal (sandbars, spits) shifting of detritus, depending on the angle from which waves approach the shore and the nature of the shifting of the detritus. Certain of the forms (abutting terraces, accumulative shelves) take shape from either longitudinal or transverse shifting of detritus. Peculiarities of the configuration of the shore have a vital influence on the development of coastal accumulative forms, since as the configuration changes, the approach angle of the waves may change, and longitudinal shifting of detritus may be retarded or replaced by transverse shifting.
